Patent GB-2185166-A (GB)
Title: Imaging apparatus
Inventor: SMITH JAMES MUIR
IPC: H04N5/353
Filed: 1984-12-13
Abstract: The sensitivity of the image sensor is controlled differently respectively during a first and a second plurality of field periods interspersed, for example alternating, one with another. The sensitivity during the respective periods may be respectively high and low so that, in effect, a greater dynamic intensity range of the sensor is obtained. The video signal portions associated with the respective periods may constitute interlaced fields on the display or may be displayed on two different monitors or in different portions of the screen of a single monitor. For missile guidance, the higher sensitivity signals display a relatively dull target while lower sensitivity signals show only the missile flare and this avoids confusion by cloud edges and the like. A CCD sensor 3 provides rapidly chargeable sensitivities, the charges from the radiation-sensing the "integration region" being clocked into the "store" by means of a pulse generator 7 which controls the timing of reverse and forward transfer of charges in such a way as to achieve control of sensitivity. Odd and even control loops 15, 16 provide for example higher sensitivity for odd lines than for even lines of the scan. <IMAGE>
